Agni is the sacred fire of ancient India, but is more than just the mere celestial fire. This book discusses the various aspects of Agni in nature from the primal creation as also his place in the Vedic sciences of Yoga and Ayurveda. Agni Rahasya discusses the deeper fires of the limbs of Yoga and within the science of Ayurveda and includes many references from the Rig Veda, the oldest book of the Hindus, relative to these sciences.
